         One of the factors contributing to the intense nature of twenty-first-century stress is our continual exposure to media – particularly to an overabundance of news. If you feel stressed out by the news, you are far from alone. Yet somehow many of us seem unable to prevent ourselves from tuning in to an extreme degree.

         The further back we go in human history, the longer news took to travel from place to place, and the less news we had of distant people and lands altogether. The printing press obviously changed all that, as did every subsequent development in transportation and telecommunication.

         When television came along, it proliferated like a poplulation of rabbits. In 1950, there were 100,000 television sets in North American homes; one year later there were more then a million. Today, it’s not unusual for a home to have three or more television sets, each with cable access to perhaps over a hundred channels. News is the subject of many of those channels, and on several of them it runs 24 hours a day.

        What’s more, after the traumatic events of Sptember 11, 2001, live newcasts were paired with perennial text crawls across the bottom of the screen – so that viewers could stay abreast of every story all the time.

        Needless to say, the news that is reported to us is not good news, but rather disturbing images and sound bytes alluding to diasater (natural and man-made), upheaval, crime, scandal, war, and the like. Compounding the proplem is that when actual breaking news is scarce, most broadcasts fill in with waistline, hairline, or very existence in the future. This variety of story tends to treat with equal alarm a potentially lethal flu outbreak and the bogus claims of a wrinkle cream that overpromises smooth skin.

       Are humans meant to be able to process so much trauma – not to mention so much overblown anticipation of potetial trauma – at once? The human brain, remember, is programmed to slip into alarm mode when danger looms. Danger looms for someone, somewhere at every moment. Exposing ourslves to such input without respite and without perspective cannot be anything other than a source of chronic stress.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the following questions.

Long before they can actually speak, babies pay special attention to the speech they hear around them. Within the first month of their lives, babies' responses to the sound of the human voice will be different from their responses to other sorts of auditory stimuli. They will stop crying when they hear a person talking, but not if they hear a bell or the sound of a rattle. At first, the sounds that an infant notices might be only those words that receive the heaviest emphasis and that often occur at the ends of utterances. By the time they are six or seven weeks old, babies can detect the difference between syllables pronounced with rising and falling inflections. Very soon, these differences in adult stress and intonation can influence babies' emotional states and behavior. Long before they develop actual language comprehension, babies can sense when an adult is playful or angry, attempting to initiate or terminate new behavior, and so on, merely on the basis of  cues such as the rate, volume, and melody of adult speech.

Adults make it as easy as they can for babies to pick up a language by exaggerating such cues. One researcher observed babies and their mothers in six diverse cultures and found that, in all six languages, the mothers used simplified syntax, short utterances and nonsense sounds, and transformed certain sounds into baby talk. Other investigators have noted that when mothers talk to babies who are only a few months old, they exaggerate the pitch, loudness, and intensity of their words. They also exaggerate their facial expressions, hold vowels longer, and emphasize certain words.

More significant for language development than their response to general intonation is observation that tiny babies can make relatively fine distinctions between speech sounds. In other words, babies enter the world with the ability to make precisely those perceptual discriminations that are necessary if they are to acquire aural language.

Babies obviously derive pleasure from sound input, too: even as young as nine months they will listen to songs or stories, although the words themselves are beyond their understanding. For babies, language is a sensory-motor delight rather than the route to prosaic meaning that it often is for adults

What point does the author make to illustrate that babies are born with the ability to acquire language?

A. Babies exaggerate their own sounds and expressions

B. Babies begin to understand words in songs

C. Babies notice even minor differences between speech sounds

D. Babies are more sensitive to sounds than are adults

Read the following passage and mark the letter A, B , C or D on your answer sheet to indicate the correct answer to each of the questions.

Ever since humans have inhabited the earth, they have made use of various forms of communication. Generally, this expression of thoughts and feelings has been in the form of oral speech. When there is a language barrier, communication is accomplished through sign language in which motions stand for letters, words, and ideas. Tourists, the deaf, and the mute have had to resort to this form of expression. Many of these symbols of whole words are very picturesque and exact and can be used internationally, spelling, however, cannot.

Body language transmits ideas or thoughts by certain actions, either intentionally or unintentionally. A wink can be a way of flirting or indicating that the party is only joking. A nod signifies approval, while shaking the head indicates a negative reaction.

Other forms of nonlinguistic language can be found in Braille (a system of raised dots read with the fingertips), signal flags, Morse code, and smoke signals. Road maps and picture signs also guide, warn, and instruct people.

While verbalization is the most common form of language, other systems and techniques also express human thoughts and feelings.

What is the best title for the passage?

A. The Many Forms of Communication                  

B. Picturesque Symbols of Communication

C. Ways of Expressing Feelings                              

D. The Importance of Sign Language

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

Because writing has become so important in our culture, we sometimes think of it as more real than speech. A little thought, however, will show why speech is primary and writing secondary to language. Human beings have been writing at least 5,000 years, but they have been talking for much longer, doubtless ever since there have been human beings. When writing developed, it was derived from and represented speech, although imperfectly. Even today, there are spoken languages that have no written form. Furthermore, we all learn to talk well before we learn to write; any child who is not severely handicapped physically or mentally will learn to talk: a normal man cannot be prevented from doing so. On the other hand, it takes a special effort to learn to write; in the past, many intelligent and useful members of society did not acquire the skill, and even today many who speak languages with writing systems never learn to read or write while some who learn the rudiments of those skills do so imperfectly.

To affirm the primacy of speech over writing is not to disparage the later. One advantage writing has over speech is that it is more permanent and makes possible the records that any civilization must have. Thus, if speaking makes us human, writing makes us civilized.

The word “acquire” in the passage mostly means _______ 

A. “help somebody learn something by giving information about it”

B. “gain something by our own efforts or ability”

C. “become aware of something by hearing about it”

D. “develop a natural ability or quality so that it improves”
